This invention relates generally to aircraft configurations, and more particularly, to an aircraft sales tool.
An aircraft, such as a rotorcraft, may include a variety of equipment options. Some of these equipment options may change performance of the aircraft. For example, some equipment options may change the range of the aircraft.
Particular embodiments of the present disclosure may provide one or more technical advantages. A technical advantage of one embodiment may include the capability to provide customers with aircraft range estimations during the buying process. A technical advantage of one embodiment may also include the capability to allow customers to see how equipment options impact aircraft range.
Certain embodiments of the present disclosure may include some, all, or none of the above advantages. One or more other technical advantages may be readily apparent to those skilled in the art from the figures, descriptions, and claims included herein.
To provide a more complete understanding of the present invention and the features and advantages thereof, reference is made to the following description taken in conjunction with the accompanying drawings, in which:
An aircraft, such as rotorcraft 100, may serve in a variety of different missions. For example, rotorcraft 100 may transport people, provide reconnaissance, and/or engage in combat. Such missions may vary in length, with some aircraft traveling longer distances when performing certain missions. In addition, some aircraft encounter a variety of different environmental conditions when performing missions, such as nautical, arctic, and desert conditions.
Aircraft such as rotorcraft 100 may be customized to perform certain missions. In particular, optional equipment may be added to rotorcraft 100 to perform certain missions in certain environments. For example, an aircraft may be equipped with weapons for performing combat missions or may be equipped with a cargo hook for hauling equipment.
A customer (including a potential customer) interested in purchasing an aircraft such as rotorcraft 100 may wish to customize the aircraft for performing a certain mission in a certain environment. In addition, the customer may desire additional optional equipment that, even if not essential for a particular mission, may still be an asset on the aircraft.
The customer may also have range requirements associated with a mission. For example, a helicopter configured to transport personnel to and from an off-shore oil platform should have enough range to travel to and from the platform without stopping for fuel.
In this and other examples, the customer may not be aware how adding optional equipment changes the range of the aircraft. In particular, for some aircraft, range may increase dramatically as weight increases, but the customer may not be aware of how each additional pound reduces the range of the aircraft. Thus, the customer may order an aircraft with optional equipment that does not satisfy the range requirements for a particular mission. If the customer was aware that a certain configuration of optional equipment resulted in an aircraft range less than the required range for a particular mission, the customer may prefer to change which optional equipment will be added onto the aircraft.
Accordingly, teachings of certain embodiments recognize the capability to provide customers with aircraft range estimations during the buying process. Teachings of certain embodiments also recognize the capability to allow customers to see how equipment options impact aircraft range.
Teachings of certain embodiments also recognize that estimations may be sufficient for the early stages of the sales experience. Thus, teachings of certain embodiments recognize the capability to provide such range estimations quickly and without the need for a lengthy and complicated engineering process.

User interface 210 receives information from and provides information to user 5. In some example embodiments, user interface 210 may be associated with a software application or web interface, such as a tablet application or a website. In some examples, user interface 210 receives information from and provides information to a customer (or potential customer). In these examples, access to user interface 210 may be controlled or limited by another user 5, such as a salesperson.
Aircraft data repository 220 stores information about aircraft available for sale. Examples of information stored in aircraft data repository 220 may include prices, descriptions, pictures, specifications and performance data. In particular, aircraft data repository 220 may store information such as weight and range information for each base aircraft available for sale.
Option data repository 230 stores information about equipment options that may be added to a base aircraft. Examples of information stored in option data repository 230 may include prices, descriptions, pictures, specifications, and performance data. In particular, option data repository 230 may store information such as weight and installation information.
Compatibility engine 240 analyzes equipment options selected by user 5. For example, compatibility engine 240 may analyze whether multiple equipment options are compatible. Two or more equipment options may not be compatible if they may not be installed on the same aircraft at the same time. Two or more equipment options may not be compatible, for example, if they share the same physical space. For example, a camera option and a weapons option may not be compatible if they must be installed in the same location. As another example, skid-gear and wheel-gear landing kits may be incompatible because they cannot be installed on the aircraft together. Compatibility engine 240 may reject a proposed selection of equipment options if they are not compatible, and user interface 210 may inform user 5 that the equipment option selection has been rejected.
Configuration assessment engine 250 analyzes a configured aircraft based on the selections of user 5. In some example embodiments, configuration assessment engine 250 estimates the range of a base aircraft selected by user 5 based on the selections of user 5.
In some estimations, range of an aircraft may be a function of environmental conditions. For example, range of an aircraft may be a function of air pressure, temperature, density, and/or viscosity. These and other environmental conditions may vary depending on location and/or altitude. A customer may not know the environmental conditions in which the aircraft will be flying, however. Accordingly, teachings of certain embodiments recognize the capability to estimate environmental conditions based on a geographic location provided by the customer.
Environmental data repository 260 stores environmental condition information for different geographic locations. In some embodiments, environmental data repository 260 provides environmental condition estimates to configuration assessment engine 250 based on the geographic location provided by user 5, and configuration assessment engine 250 estimates the range of a configured aircraft based at least in part on the provided environmental condition estimates.
In some embodiments, user 5 provides a three-dimensional geographic location, such as by providing an altitude paired with latitude/longitude coordinates or with an address (such as a city or street address). In some examples, user 5 provides an estimated flight altitude, which may be measured, for example, from above sea level or above local elevation. If user 5 provides an estimated flight altitude above local elevation, environmental data repository 260 may determine the ground elevation at the geographic location (e.g., the elevation of Denver, Colo.) and add the flight altitude provided by user 5 to yield an estimated flight altitude above sea level.
User 5 may not necessarily know what elevation at which the aircraft will be flying. Accordingly, in some embodiments, user 5 may provide a two-dimensional geographic location, such as by providing latitude/longitude coordinates or an address. In this example, environmental data repository 260 may determine the flight altitude based on the ground elevation at the geographic location and a standard flight altitude. In some examples, the standard flight altitude may be unique to each base aircraft based on the capabilities of each base aircraft.
Environmental data repository 260 may provide environmental condition estimates to configuration assessment engine 250 based on the geographic location provided by user 5. In one example embodiment, environmental data repository 260 may estimate environmental conditions based on the International Standard Atmosphere (ISA) model. The ISA model is an atmospheric model of how pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes. ISA may provide a common reference for temperature and pressure and include tables of values at various altitudes, plus some formulae by which those values were derived. The International Organization for Standardization (ISO) publishes the ISA as an international standard, ISO 2533:1975. In some embodiments, standards other than the ISA model may be used. For example, other standards organizations, such as the International Civil Aviation Organization (ICAO) and the U.S. Government, publish extensions or subsets of the same atmospheric model under their own standards-making authority. In addition, environmental data repository 260 may allow deviations from a standard model based on known natural deviations (e.g., known geographic locations that deviate from the standard model) and/or input from user 5. In addition, the environmental condition estimates provided by environmental data repository 260 may be adjusted to provide a safety tolerance for range calculations.
In operation, according to example embodiments, user interface 210 receives, from user 5, identification of a base aircraft, at least one equipment option, a number of passengers, and a geographic location. Aircraft data repository 220 provides the weight of the base aircraft identified by user 5. Option data repository 230 provides the weight of at least one equipment option identified by user 5.
In addition, aircraft data repository 220 may provide aircraft sales information about the base aircraft, including a picture, a price, and a description associated with the base aircraft. In some embodiments, this aircraft sales information is provided by aircraft data repository 220 and displayed by user interface 210 in response to identification of the base aircraft by user 5. In other embodiments, the aircraft sales information is not provided by aircraft data repository 220 and displayed by user interface 210 in response to identification of the base aircraft by user 5. For example, user interface 210 may display the aircraft sales information for a base aircraft before user 5 selects the base aircraft (e.g., user interface 210 provides aircraft sales information about a variety of aircraft, and user 5 is provided an opportunity to select a base aircraft).
In these example embodiments, configuration assessment engine 250 may estimate a range of the configured aircraft identified by user 5. For example, configuration assessment engine 250 may estimate an overall weight of the configured aircraft as a function of the weight of the base aircraft (such as provided by aircraft data repository 220), the weight of the at least one equipment option (such as provided by option data repository 230), and a weight associated with the number of passengers identified by user 5. In addition, configuration assessment engine 250 may receive estimated environmental information from environmental data repository 260, which may estimate the environmental information from geographic location information provided by user 5. Configuration assessment engine 250 may then estimate the range of the configured aircraft based on the overall weight and estimated environmental information.
Configuration assessment engine 250 may estimate the range of the configured aircraft based on the overall weight and estimated environmental information in a variety of ways. In one example, range information may be determined for each base aircraft as a function of weight and environmental conditions. For example, each base aircraft may have pre-flight tables and graphs that allow the range to be estimated as a function of weight and environmental conditions; in this example, configuration assessment engine 250 may apply formulas representative of these tables and graphs (e.g., each formula may be a curve fit from a pre-flight range graph). In this manner, configuration assessment engine 250 may rely on preexisting range calculations to estimate range for a potential customer.
In the preceding example, configuration assessment engine 250 may not necessarily estimate range as a function of drag. Rather, 100 pounds of passenger or options inside the fuselage may be treated as equal to 100 pounds of equipment installed outside the aircraft. Teachings of certain embodiments recognize that ignoring drag may simplify calculations while allowing for sufficient range estimation for sales purposes.
Teachings of certain embodiments also recognize, however, the capability to improve range estimations by accounting for how drag may reduce range of an aircraft. In one example embodiment, each equipment option may have an associated drag penalty (for those equipment options that do not cause drag, the drag penalty may be nominal or zero). In this example, configuration assessment engine 250 may estimate the range of the configured aircraft as a function of these drag penalties. In one example, a camera installed outside the aircraft may be estimated to reduce range by five percent; in this example, configuration assessment engine 250 may apply a five percent penalty to the range calculations described above.
User interface 210 may provide the estimated range to user 5. User interface 210 may also provide additional information about the configured aircraft, such as a price of the configured aircraft (based, for example, on the price of the base aircraft, the price of the equipment options, and delivery costs), a description of the configured aircraft, a picture of the configured aircraft, and a delivery date for the configured aircraft.
Information panel 320 provides additional information about the configured aircraft and its range. In the example of
